                ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky
 Overcast skies during twilight that quickly cleared out.  Skies were
 wonderful until 4AM when orographic clouds formed overhead and closed us
 down for the remainder of the night.
 No problems tonight and the guide on slit for the dis slitviewer worked
 like a champ.
